SOLDERING APPARATUS. A.

SPECIFICATION forming part of Letters Patent No. 467,694, dated January 26, 1892.

Application filed December 14, 1888. Serial No. 293,607. (No model.) A

.To all whom t may concern:

Be it known that I, CHARLEs LEWIS WA- GANDT,acitizen of the United States, residing in the city of Baltimore and State of Maryland, have invented certain new and useful Improvements in Soldering Apparat-us; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which [o it appertains to make and use the same.

My invention relates to devices whereby the soldering of various articles of manufacture, in large numbers, maybe conveniently, rapidly, and cheaply effected; and it is the object of my improvements to insure a steady and continuous flame in the soldering-tool; to provide for the simple and direct distribution of the compressed air and combustible gas to a number of such tools, and to secure zo other advantages.

With such objects in' view my invention consists in the apparatus hereinafter particularly set forth.

In order to make my invention more clearly understood, I have shown in the accompanying drawings means for carrying the same into effect.

In said drawings, Figure l is a sectional elevation of so much of a soldering appara- 3o tus embodying my invention as is necessary for the illustration of the same. Fig. 2 is a sectional view of the connection or Y, by means of which the compressed air and combustible gas are combined preparatory to be- 3 5 ing conducted to the soldering-tool.

Referring to the drawings, A indicates an air-compressing apparatus of any suitable construction, connected by a pipe a with a primary compressed-air reservoir B.

4o C is a secondary reservoir connected with the rst by means of a pipe h, in which pipe and intermediate between the two reservoirs is a pressure-regulator D.

25 indicates the pressure-gage of the primary reservoir, and at 2O is shown a similar gage carried by said secondary reservoir. The pressure-regulator D may be of any wellknown or suitable description, and will be set to maintain a uniform pressure-say of twenty 5o pounds-in the reservoir O, while the average pressure in reservoir B is, say, twenty-five pounds.

E is the main compressed-air pipe leading from the secondary reservoir of the above-described apparatus to the sets of ranges of sol- 5 5 dering-tools.

It will be seen that by these devices while the Vpressure in the cylinder B is continually fluctuating or pulsating by reason of the intermittent action of the compressor A the 6o pressure in the reservoir C and main air-pipe E will always be uniform. Instead of an intermittent or pulsatory action of the heatingllames in the soldering-tools hereinafter referred to, and to which branches of pipe E lead, I obtain a steady and uniform flame and heating action highly favorable to economy of heatand of gas and to the eiiiciency of thev apparatus.

F indicates a floor, of which there will pref- 7o erably be a series, one above the other.

H is a work-bench supported at suitable height above said floor and adapted to carry the soldering-tools, their holders, and the articles which are to be operated upon.

G is a gas-pipe leading from an ordinary gas-service meter M, to which latter ordinary illuminating-gas is supplied at the usual slight service-pressure. The pipe G extends with the pipe E through the iioor F and upward 8o through the various floors of the series, the flow of air and gas through such main pipes being controlled and adapted to be stopped by valves e and g, by which valves the supply of the whole system may be cutoif.

E E G G are branches extending horizontally at right angles to and of smaller diameter than the main pipes E G, with which latter they are connected through the medium of suitable couplings e g. These branch 9o pipes. extend beneath and are supported from the under side of the bench I'I, and are provided at intervals with suitable couplings or Ts I I', from which latter compressed-air conduits 'L' and gas-conduits t" extend upward 95 through the bench and connect with the branches Z Z of Ys L. Valves jj serve to cnt off or regulate the ow of air and gas through the conduits fi i".

The Ys L are constructed, preferably, as roo shown in Fig. 2, and consist, preferably, of the three branches Zl Z Z2, through the first of which the compressed air is supplied, through the second of which the gas enters, andin the 5 third of which the gas and air are mingled preparatory to being conducted to the soldering-tool. The branch Z is provided with a partition m4 and contracted supply-orifice m3, situated preferably at the rear or outer end to f the branch, while the branch is provided at its point oPj uncture with the former branch with a partition Z4 and iine jet-orifice Z3. It results from this construction that the supply of gas is limited and cannot be so increased I as to be Wasted,and that the action of the ne jet of heavily-compressed air in the larger chamber, into which it is discharged, cannot cause a backing up of the gas or cut off its flow, so as to extinguish the flame, but, on the zo contrary, accelerates the forward movement of the gas and becomes thoroughly mingled With it in such manner as to give the .maximum heating power.

The branches Z2 of the various Ys of the above-described system are connected by flexible tubes K with the soldering-tools N. These latter may be of various descriptions-such as ioating-irons, seaming-irons, tinners irons,

dac-as indicated in the drawings. v3o The compressed-air branch pipes E arel slightly inclined downward from their points of connection with the main pipe E, as indicated in Fig. l. At their outer and lower ends said branches connect with the upper 3 5 ends of traps O, which are provided at their lower ends with blow-off cocks o. By these devices the water of condensation is constantly withdrawn from the compressed-air branch pipes, the flow of air through the same left unimpeded, and' regularity in the ames of 4o the soldering-irons secured. Each branch pipe E and Gr is provided at or near itsjunction with the, main supply-pipe with a valve e2 or g2, by which the flow of air' or gas may be cut off from that wing of the establishment the soldering-tools of which are situated upon the lines of said pipes and such section of the establishment readily thrown out of operation, when desired, without impairing the supply or opera-tion of other parts of the 5o system. The supply to all ofthe branch pipes and the operation of the Whole system is discontinued, when desired, by the cu t-oif valves g and c.

l do not claim any improvement in pressure-regulators, broadly, or in the partcula kind of regulator herein employed.

Having thus described my invention, whatl claim is- The combination, in a compressed-air and 6o gas soldering apparatus, with the main air and gas supply pipes, of the lateral gas-supply branehes, the corresponding lateral compressed-air-supply branches downwardly inclined toward their outer ends, the series 0f 65 soldering-tools arranged along and connected with said branches, and the trap O, situated at the lower end of said comp-ressed-air-supply branch, substantially as set forth.

In testimony whereof I affix my signature in 7o the presence of two witnesses.
